Don't worry about it. I work at a LQS, and we are friends with the other LQS in town. Our employees shop at the other shop when we can't find what we need where we work. And vice versa. We make fleece blankets on a blanket-stitch machine at the store, and most of the time, the fabric is from JoAnn's. It's good business to not worry about whether the fabric came from another shop. One of our employee keeps saying, "we're in the friend business." It's always a treat to have customers come back and show us what they've made.
